Global wave energy generation capacity is potentially as large as presently installed hydro power and likely larger than presently installed nuclear power. Ireland and the UK (Cornwall & Scotland) have some of the highest generation capacity of wave resources in the world

With a staggering global resource, wave energy has the potential to be the largest source of clean energy. Wave energy technologies capture the movement of ocean and sea waves and use it to create energy - usually electricity. The energy created depends on the speed, height and frequency of the wave, as well as the water density The uninterrupted waves breaking at the coastlines are sometimes strong and sometimes weaker. These waves have tremendous potential energy round the clock and are free-of-charge. If the potential of these waves is fully utilized. They can satisfy 40% of the worldwide power demand and this output is equal to 700 to 800 nuclear power stations Wave Energy Potential. (Boyle at al 2012) As you can see from the map, the wave power availability increases rapidly once westerly winds begin to prevail from 30º up to 60º. As expected, coastlines exposed to these westerly winds have large power figures that range between 25 and 100 kW/m. The above 60kW/m figures become increasingly common.

In addition, a large potential for wave power systems exists in the British Isles and the Pacific Northwest of the United States. Estimates of the annual wave energy potential along the continental shelf of the U.S. coasts range between 1,170 and 2,640 terrawatt-hours, equivalent to 33-65 percent of U.S. electricity demand in 2015 Wave power potential averages between 50 and 70 kW per meter of wave front in deep water off the Hebrides, Fig. 5.

Ocean wave energy can be used to generate electricity without the limitation of time. In Thailand, the ocean wave energy potential should be assessed on both coasts because Thailand has the Gulf of Thailand (GOT) on one side, and the Andaman Sea on the other. The GOT is a shallow ocean with low ocean wave height Overtopping devices consist of a ramp or a tapered channel that forces the water of incoming waves to rise up and spill into a pool or reservoir. In this way, since the water surface of the reservoir is elevated relative to the ocean surface, the energy of the waves has been converted to potential energy
